Question

What is difference between electrolysis and electrolytic reduction

Answer 1

1. In electrolytic reduction graphite electrodes whereas in electrolytic refining, the anode is made of the impure metal which is to be purified and the cathode is made from that pure metal.

2. Electrolyte used in electrolytic refining is the metal sulfate with acid (acid is usually added to increase the conductivity) whereas in electrolytic reduction molten chloride form of the solution is used

Electrolyte is a compound in aqueous solution or in fused state splits in to ions on passing electricity.

Electrolysis is the process, in which, on passing electricity through an electrolyte causes ionization of electrolyte and movement of the cations towards cathode and anions towards anode.
